Nice write-up of amplifier classification at Gadget Guy
Apr 30th
If you’re interested in all things audio and want to know a little more about amplifier classification, Val Quinn has done a pretty decent job over at Gadget Guy.
It’s not your normal consumer electronics fare and it’s well worth a read. Val does a good job in making this quite technical subject a surprisingly easy read.
The only thing I would add from a technical viewpoint about Class-D amplification is the need to shield the output stage (the “money” end) of the amp. The way Class-D amps get their efficiency, as Val writes, is by turning the audio signal into a More >
Panasonic DMR-BW880 storage: Japan gets 1000GB, Australia only gets 500GB

Q&A – Who do the speed ratings on compact flash cards mean?
Apr 10th
A. Compact Flash (CF) cards are used in digital SLR cameras and some video cameras so just as with SecureDigital (SD) cards, there’s a need to have a fast-write card in certain applications.
CF cards have a different speed rating to SD cards. In fact, it’s the same speed rating as used by CD-ROMs. It’s a multiplier “x” rating where 1X-speed is 150KB/second.
This chart will give you a rough idea of what you can expect on the streets:
Rating Speed (MB/s) 6x 0.9 32x 4.8 40x 6.0 66x 10.0 100x 15.0 133x 20.0 150x 22.5 200x 30.0For basic digital photography, again, More >
